RESUMO
Background: Antibiotic resistance being the critical issue faced by medical field, especially by Gram negative bacteria. It is a great threat in the case of both hospitals acquired and community acquired infections. They possess various mechanisms for their survival. The widespread resistance in Gram negative bacteria has necessitated evaluation of the use of older antimicrobials such as polymyxins. Polymyxins are disfavoured owing to their potential clinical toxicity, especially nephrotoxicity. Thus, they got abandoned in the sixties. But now they are re- emerged and used as last resort antibiotics. Methods: 274 isolates of Enterobacterales including Klebsiella pneumoniae, Escherichia coli, Citrobacter spp. Enterobacter spp. was collected from various diagnostic microbiology laboratories in Kerala. The polymyxin resistance among Enterobacterales by broth disk elution method recommended by CLSI. Results: In this study prevalence of multi drug resistant is 37% and extensively drug resistant strains is 25%. And the threatening fact is that the colistin also shows resistance among Enterobacterales (9.2%). Conclusions: Though the resistance to Polymyxin B is to the lesser side in the present study, increase in resistance to the agent is being documented globally elsewhere. So, rational use of Polymyxin B is warrantied as we could cherish polymyxin B as a 搇ife - saving drug� to avoid no drug available. Knowledge of antimicrobial resistance and development of new antimicrobial agents and improved treatments are essential in the current situation.
RESUMO
Background: Oral infections caused by microorganisms have led to increased risk of oral health problems like dental caries (DC). Streptococcus mutans and Candida albicans are the organisms responsible for DC. The goal of the presented study was to investigate the potential of probiotics to prevent and treat DC. An in vitro assay was developed to investigate several probiotic strains for their ability to inhibit the aforementioned oral pathogens. Methods: 40 oral isolates of Streptococcus mutans and 51 oral isolates of Candida albicans were tested for probiotic activity against Lactobacillus acidophilus and Lactobacillus rhamnosus using agar overlay interference technique as prescribed by Fleming et al. Results: The zone of inhibition shown by L. acidophilus was higher than L. rhamnosus against Streptococcus mutans and Candida albicans. Conclusions: In conclusion the two probiotic strains L. acidophilus and L. rhamnosus exhibited inhibitory activity on S. mutans and C. albicans respectively in vitro.

RESUMO
Background: Diagnosis of jaundice involves a range of tests. The liver function tests are done in all to arrive at a diagnosis and then manage the case appropriately. With advancing age, the incidence of liver disease increases. Understanding these changes is important for the management of liver diseases in the elderly. We conducted this study to find the difference in mean levels of Liver enzymes in younger and older age group of patients suffering with jaundice.Methods: It was a prospective observational study. All patients admitted with jaundice in the medicine ward satisfying inclusion/exclusion criteria were enrolled. The results of liver function tests in younger age and older age participants were then compared.Results: Total 100 participants were enrolled during the study period. 53 were enrolled in group one and the rest in group two. Anorexia (90%) was the most common symptom followed by abdominal distension (54%). The total bilirubin (8.8±4.7) as well as conjugated bilirubin (3.4±2.8) were higher in group one though they were not significant statistically (p=0.10 and 0.25 respectively). Mean AST and ALT levels were much higher in group 1 and statistically significant (p values <0.004 and 0.002 respectively). Conversely the mean PT values were higher in group two (p=0.02).Conclusions: Although the symptom severity may be more in elderly, the LFTs are not deranged proportionately. So there is a need to devise separate cut offs and these have to be lower for the older age group patients with jaundice. More studies with larger sample size are required to confirm the results.
RESUMO
Background: Though the actual symptoms of any haemostatic abnormalities in patients of solid malignancies are not seen commonly screening in all such cases can guide us to correct those abnormalities in time and improve the outcome. The present study is undertaken with an objective to find out coagulation disorders in patients of solid malignancies and compare their levels according to the stage of the cancer.Methods: A prospective study was undertaken in a tertiary care centre in Maharashtra, India from December 2010 to September 2012. Total 102 cases with malignancies diagnosed on histopathology/cytological examination were tested for BT, CT, Platelet count, PT, APTT, TT and D-dimer levels. These tests were repeated on first postoperative or post chemotherapy day wherever possible. Early and advanced stages of cancer were divided according to the spread of the tumor. Results were compared between the two. DIC cases were also noted.Results: Out of 102 cases studied, haemostatic abnormalities were more common in adenocarcinomas that too in mucin secreting adenocarcinomas. The percentage of cases with increased D-dimer values was higher in the advanced disease compared to early disease. The PT, APTT, TT and platelet count showed statistically significant differences between the early and advanced disease groups. Compared to preoperative values, postoperative values were abnormal but the change was not statistically significant.Conclusions: Screening for coagulation profile in all solid malignancies can help to predict the chances of complication and therapeutic interventions can be done.
RESUMO
Background: Abnormal uterine bleeding is one of the commonest complaints in women and when it occurs without organic lesions like tumor, inflammation, it is called as dysfunctional uterine bleeding. Aim of current study was to find out the histopathological pattern of endometrium in Abnormal Uterine Bleeding (AUB) also to study organic causes of AUB. Methods: Specimens received as endometrial curettage and hysterectomy specimens were studied followed by correlation of histopathology with age and clinical presentation. Results: The patients were mainly from the age group of 30-49 years (74.24%). The most common menstrual disorder was menorrhagia (46.86%). In dysfunctional uterine bleeding the most common histological pattern of endometrium includes proliferative endometrium (22.8%) followed by endometrial hyperplasia (19.40%), atrophic endometrium (7.16%), secretory endometrium (5.97%), irregular shedding [1.80%], irregular ripening (1.20%) and anovulatory endometrium (0.59%). Organic lesions encountered in AUB cases were leiomyoma (17.92%), endometrial polyp (1.79%), endometrial carcinoma (1.50%), endometriosis (0.59%) and choriocarcinoma (0.29%). Conclusion: It is important to know the histological pattern of the endometrium like proliferative endometrium, endometrial hyperplasia, atrophic endometrium, secretory endometrium, irregular ripening and shredding and organic lesions in patients diagnosed as AUB in different age groups since recognition of these conditions will help and will avoid further complications.
RESUMO
The ethanolic extract of S. robusta resin (10 and 30 % w/w applied locally in excised and incised wounds) produced a dose-dependent acceleration in wound contraction and increased hydroxyproline content and tensile strength of wounds in rats. The results demonstrate wound healing activity of ethanolic extract of S. robusta resin.
